Got an error on the Timeline Page

Reported by: sdegrande Owned by: Steffen Hoffmann
Priority: high Component: DiscussionPlugin
Severity: critical Keywords:

When displaying the Timeline with DiscussionPlugin enabled, I got the following Trac error :

Event provider DiscussionTimeline failed for filters "Forums changes": TypeError: tuple indices must be integers, not str

I use Trac 1.1.1 + Python 2.7.3 + TracDiscussion 0.9dev-r13945

Please find attached a patch that fixes it for me.

Would you explain the proposed change a bit more, please?

AFAIKS the patch is badly formatted and patched Python code will not run due to indentation issues. So I doubt that you tested with the patched code. Furthermore the patch just decomposes the list comprehension, what should have zero effect on the reported issue with tuple indices. But maybe I'm overlooking something here?

We should add unit tests for that, see discussionplugin-t11902-r14133.diff.

The row variable is a tuple in discussionplugin/0.11/tracdiscussion/

        return [dict(zip(columns, row),
                for row in cursor]

Sorry, I did not see that you commented this ticket 2 weeks ago, hasienda.

Sorry for the bad formatted patch (I use it and it runs, so something went wrong when I uploaded the diff).

As far as I understand it, the error comes from the execution of rowstatus?, because row is not 'yet' a dict when used in the call to topic_status_to_list() (I can be wrong, I'm not a python expert at all).

That's why, in my patch, I first retrieve the dict(zip(...)) before to call topic_status_to_list(rowstatus?)

jun66j5's patch is indeed much better, in my humble opinion.

Thank you Jun for helping with the explanation and handling the other ticket. I'll apply your smaller fix, happily extending the unit test harness.

In 14139:

DiscussionPlugin: Prevent TypeError: tuple indices must be integers, not str, refs #11902.

Thanks to Samuel Degrande for the original report and to Jun Omae for
explaining the issue and providing both, an elegant fix and improved unit tests.
